What Is The Difference Between PVC, UPVC, And CPVC

What is the difference between PVC, UPVC, and CPVC? IFAN will answer for you.IFAN factory has 30+ years manufacture experience supporting color /size customization support Free Samples.

PVC

PVC is polymerized from vinyl chloride monomer (VCM). The material has the characteristics of non-toxic, anti-aging, acid and alkali resistance. Very suitable for chemical pipeline use.

PVC (PolyVinylChloride) has seven grades (SG1-SG7) according to the hardness and performance of the material, and the density is 1.4g/cm3. Below SG4, it is generally a soft product, and a large amount of plasticizer needs to be added during molding. It is mainly used to make artificial leather, wires, cable insulation layers, seals, etc.

SG5 and above are hard products, mainly used to manufacture various pipes. Such as drainage, electricity, post and telecommunications, communication pipes and accessories, various plates, plates, profiles, etc.

The molding shrinkage rate of PVC is 0.6-1.5%, and it has good mechanical properties. And excellent electrical properties, self-igniting, strong acid and alkali resistance, good chemical stability, low price, widely used general-purpose plastics. However, because its operating temperature is not high, the highest is about 80°C, it is difficult to develop.

CPVC

CPVC is a polymer material modified by chlorination of polyvinyl chloride (PVC). After PVC resin is chlorinated, the chlorine content increases from 56.7% to 63-69%. Increased chemical stability, improved heat resistance, acid resistance, alkali resistance, salt resistance, oxidation and corrosion resistance of the material.

UPVC

PVC raw material to add a certain amount of solid (without plasticizer) additives made up of a mixture, called hard polyvinyl chloride (UPVC).
